tensorflow:: ops:: DecodeCSV

#include <parsing_ops.h>

Convert CSV records to tensors.

Summary

Each column maps to one tensor.

RFC 4180 format is expected for the CSV records. ( https://tools.ietf.org/html/rfc4180 ) Note that we allow leading and trailing spaces with int or float field.

Args:

  • scope: A Scope object
  • records: Each string is a record/row in the csv and all records should have the same format.
  • record_defaults: One tensor per column of the input record, with either a scalar default value for that column or an empty vector if the column is required.

Optional attributes (see Attrs ):

  • field_delim: char delimiter to separate fields in a record.
  • use_quote_delim: If false, treats double quotation marks as regular characters inside of the string fields (ignoring RFC 4180, Section 2, Bullet 5).
  • na_value: Additional string to recognize as NA/NaN.

Returns:

  • OutputList : Each tensor will have the same shape as records.
